    Thanks ! It ran well - but - I have it on a tall stand & moved it back and forth - minor jiggling which may or may not have contributed to the failure.

    Sure won't do that again !

    I have the same problem with this model.

    I brought it back from getting fixed because the whole unit just shut down one day, there was no sound or picture. When I brought it back home, It worked for 3 months then all of a sudden there was a loud ping, like something being overloaded. It resulted with having no picture or sound. The RED indicator light at the front is on when I turn the unit on but there is no sound or picture.

    The tv repair shop says that it is the DEFLECTION board model #PB9582E is to blame for this problem.

    I went online to find the part but I could find only find one place that has this board and they want $357.41. Hahahaha nope, I am not paying that. You can pick up a new 40 inch LCD for $300 more.

    You see the first visit to the shop left me $250.00 light and I got 3 months out of the deal. Now even though my tv guy will put in the part for free, it still runs me a total of $600 in total.

Toshiba did have a problem with a protection ic that would fail. It is possible that this is the problem. But some trouble shooting will need to be done buy a repair shop.

I have Laars Lite2 125k BTU Propane. pilot stay lit and after some time hear click sound in gas valve but it will not fired up and also pilot goes off right away.


It sounds like you need to replace the pilot generator. This is the metal cylinder that sets in the flame of the pilot and supplies voltage to the system. When it gets weak, it will support the pilot valve to remain open, but when the main valve tries to open the pilot generator cannot provide enough electricity, and everything shuts down. It's a prime suspect in your situation.

It runs out of fuel


sound like pilot lite is not getting thermocouple hot.
check that pilot lite flame is extending out to and touching thermocouple. If not, clean out pilot lite orface and pilot lite gas feed pipe all the way back to the main gas valve if necessary.
If pilot lite flame is touching thermocouple, then replace thermocouple

Why does pilot light turns on gas burner only to have it go out about 10 seconds later? 30 to 40 sec later repeats,without lighting. What is problem? once in awhile, it will light..not often. The burner...


Hello
Sounds like the thermocouple is going bad.The thermocouple is a thin tube that runs from the pilot lite to the gas valve.
What it does is it sences the heat from the pilot lite and keeps the gas valve open to allow the pilot to stay on.
This can be easily repaird by shutting off power and gas to your heater and removeing the thermocouple from the gas valve,then unclip or unscrew it from the pilot lite area.
Any plumbing supply store or home depot or lowes should have these.

Once you get a new one,install to gas valve and pilot lite area then turn on power and gas to heater and follow pilot lighting procedure,you may need to hold gas on for 60 seconds.

Here is a picture of the thermocouple so you know what to look for.

How do i start the pilot light on a JGBP28wek6ww


That model is an electronic ignition, ther isn't a standing pilot on it(no liitle flame that stays lit). Light the burner by pushing in on the knob and turnlig to "LITE" position, you will hear a clicking noise the sound of the electric spark igniting the burner, turn the knob to adjust the flame size. Keep in mind that all igniters spark whenever any of the knobs are turned to the "LITE" position. Good luck !

Cleaning lady accidently sprayed windex near our 6 yr old gas GE profile stove. It now makes a clicking noise. What should I do.


Hello there:
the clicking sound that you are hearing is the igniotor trying to lite the pilot s but the pilot lite is out what you can do is first lite all of the pilot lites manually and then start the burners normally as you would and now they should work ok
Also if you contact you local gas/ electric company they will come to your home and lite this stove for no charge ok?
I hope this is very helpful for you
Best regards Michael

I have a 20 watt peavey micro bass, and what happened was my brother knocked it over and will not turn on. I checked the fuse and it was ok, any help you would be great.


When it was knocked over it may have cracked the main circuit board, but does the pilot light come on at all? If the pilot light comes on but no sound is output from the speaker try plugging some headphones into the head phone jack and then turn it on and see if you can hear sound in the headphones. I have had a similar problem before and the main speaker had gone bad but it would still play thru the head phone jack.
